The lazy approach to communication mandates that you pick a new tool. And it will fail, because communication is about choosing what to communicate, how often, on which channels, to whom, while making whose who communicate accountable.
The lazy approach to communication mandates that you send an email. And it will fail, because communication works better face to face, over a period of time, in a two-way fashion, and when people communicating are actually open to changing their plans based of feedback.
The lazy approach to communication mandates that you go around the room. And it will fail, because communication needs an agenda, a plan, preparation, somebody who ensures we stick to the plan, somebody who takes the responsibility to cut others short.
The lazy approach to communication mandates that you speak your mind. And it will fail, because nobody wants to listen to you rambling while you attempt to clarify your opinion, your idea, your thoughts in front of an audience, just because you could not take ten minutes to write something down in advance.
Communication is hard work. And companies should stop half-assing it.
